NAC-04-472

Power Line Filter Modules Overview

The NAC-04-472 is a single-phase EMC/EMI power line filter module manufactured by Cosel USA, Inc. It is designed for chassis mounting and supports a continuous current of 4 A at voltages up to 250 V AC or DC. The unit features a single-stage filtering architecture utilizing terminal block connections for circuit integration. This component serves as an interface between the power source and downstream equipment to mitigate electromagnetic interference.

Power Line Filter Modules Feature Summary

• Provides attenuation of common mode noise within the frequency range of 150 kHz to 1 MHz
• Utilizes a spring-loaded captive terminal block design for secure electrical connections
• Constructed with a compact form factor suitable for dense chassis installations

Power Line Filter Modules Applications

• Industrial control systems requiring EMI suppression
• Medical equipment power input stages
• Information technology equipment (ITE) power conditioning

Power Line Filter Modules Procurement Notes

Verify that the specific application voltage does not exceed the 250 V rating and that the load current remains within the 4 A limit. Confirm that the terminal block connection method aligns with the system's wiring infrastructure. Ensure the physical dimensions fit the designated chassis space before finalizing procurement decisions.

Power Line Filter Modules Selection Notes

Select this model when a single-stage solution is sufficient for noise reduction requirements. Consider the NAC-04-472-D variant if DIN rail mounting is preferred over chassis installation. Evaluate the need for additional filtering stages if higher attenuation levels are required beyond the standard single-stage performance specifications.

Power Line Filter Modules Part Context

This component belongs to the Cosel NA series of power line filters. The series offers various current ratings and mounting options to accommodate different industrial and commercial power integrity needs. The NAC-04-472 specifically addresses low-current applications requiring reliable chassis-mounted noise filtration.

Power Line Filter Modules Replacement Considerations

The NAC-04-472-D is a related variant offering identical electrical characteristics but featuring DIN rail mounting instead of chassis mounting. Verify mechanical compatibility when substituting between these two models.
